[QUOTE="sequent, post: 41, member: 1"] Although common engineering practice might not recommend it, we found out that switching power supplies of the same voltage are quite happy to operate in parallel. All will contribute to the load. If you do not have more than a few relays on at the same time, probably one 24V power supply will be enough. The Building Automation can supply up to 3A on the 5V line. Each relay takes about 80mA, so if you have many relays on, just add a 5V supply to one of the 8-Relays. [/QUOTE]
